Extract:
Question 1 of 5
A nurse is caring for a client who is diagnosed with a deep vein thrombosis (DVT) and is receiving heparin. The client asks the nurse how long it will take for the heparin to dissolve the clot, which of the following responses should the nurse give?
Correct Answer: B
Rationale: Heparin prevents new clot formation but does not lyse existing clots, which the body gradually reabsorbs.
Question 2 of 5
A nurse prepares to administer vancomycin 15 mg/kg/day divided equally every 12 hr. The client weighs 198 lb. How many mg should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: Calculated: 198 lb ÷ 2.2 = 90 kg; 15 mg/kg/day × 90 kg = 1350 mg/day; 1350 ÷ 2 = 675 mg per dose.
Question 3 of 5
The nurse is educating a client on the possible side effects associated with quinapril (Accupril). Which of the following side effects are associated with this medication classification? (Select All that Apply)
Correct Answer: B,D,E
Rationale: Quinapril, an ACE inhibitor, can cause first-dose hypotension, dry cough, and orthostatic hypotension, but not hypokalemia or hepatotoxicity.
Question 4 of 5
The nurse is preparing to administer digoxin (Lanoxin) to a client experiencing atrial fibrillation. Which of the following electrolyte imbalances would the nurse assess to reduce the incidence of toxicity with digoxin (Lanoxin)?
Correct Answer: B
Rationale: Hypokalemia enhances digoxin's cardiac effects, increasing toxicity risk, so potassium levels must be monitored closely.
